The MKS a-Baratron® manometer is an advanced high-performance absolute unheated capacitance manometer developed specifically for use in vacuum and pressure measurement applications where accuracy and repeatability are crucial to process success. They use state-of-the-art digital architecture throughout to produce the highest possible long-term performance and reliability. These manometers operate on +15 VDC to +30 VDC input voltage, and have a standard 0 to 10 VDC analog output signal. Full Scale measurement ranges from 1Torr (133.3 Pa) to 1000 Torr (133.3 kPa) are available.

Features & Benefits:

  • All products are specified in percent of reading for best accuracy and improved process yield
  • Direct measurement of chamber total pressure independent of gas type or composition, eliminating need for lookup tables and conversion factors
  • Best-available long-term output stability ensures state-of-the-art process repeatability in nearly any application
  • Inconel® and Incoloy® nickel alloy construction of basic sensor operates without damage in virtually any chemical environment, including halogens, deionized water and steam, and ozone
  • High overpressure limit ensures reliability from occasional system mishaps
  • Push button zeroing

Applications:

a-Baratron® manometers are used in a wide variety of applications including vacuum furnaces, freeze-drying of fruits and vegetables, gas lasers, automotive component testing, bottle coatings, and vacuum distillation.
